Effects of alloying elements on glass formation, mechanical and soft-magnetic properties of Fe-based metallic glasses

Review on the Research and Development of Ti-Based Bulk Metallic Glasses

“…Much research shows that atomic size differences between the constituent elements and the heat of mixing play important roles on the glass formation of BMGs [135][136][137]. Recently, it has been found that the electronegativity difference also influences the GFA of Al- [138,139], Fe- [140], and Ti-based BMGs [90][91][92][93]. In order to evaluate the GFA of Ti-based BMGs, Zhao et al [93] calculated the parameters including the atomic size difference δ, electronegativity difference ∆x, and the enthalpy of mixing ∆H mix for typical Ti-based BMGs.…”

Lightweight Ti–Zr–Be–Al bulk metallic glasses with improved glass-forming ability and compressive plasticity

“…A typical Ti-Zr-Be glassy composition is Ti 41 Zr 25 Be 34 [11], possesses a critical size of 5 mm. In order to further improve the GFA and mechanical properties of Ti-Zr-Be glassy alloys, alloying method, which has been widely used in improvement of GFA and mechanical properties for BMGs is adopted [13][14][15][16]. In this paper, we developed a new Ti-Zr-Be-Al glassy system with the addition of Al based on the reported Ti 41 Zr 25 Be 34 glassy alloy and a series of metallic glasses with good GFA and mechanical properties have been obtained.…”

Effects of Nitrogen on the Glass Formation and Mechanical Properties of a Ti-Based Metallic Glass

“…As a result, the alloy has good ability to resist shearing and therefrom possesses higher yield strength [42]. A denser packing structure also indicates that bonding lengths between adjacent atoms are shorter, i.e., a smaller characteristic length k, giving rise to stronger bonding forces among constitute elements [43,44] and higher yield strength eventually [44]. Therefore, the increment in the strength can be well interpreted as a consequence of bonding type and bonding length changes resulted from the N addition.…”
